我正在尝试从应用程序连接到本地clickhousedb以执行一些原始查询。当我试图打开连接时，问题出现了。它从不从方法调用返回。
clickhousedb是在docker容器中启动的。

using (ClickHouseConnection conn = connFactory.CreateConnection(new ClickHouseConnectionSettings(connectionString)))
            {
                var cmd = conn.CreateCommand();

                cmd.CommandText = "select * from default.table_name";

                conn.Open(); // it never goes past this line
                using (var reader = cmd.ExecuteReader())
                ...

我想在会议结束后开通一个连接 conn.Open() 并继续执行下一行执行读卡器的程序。
注意：如果我尝试从python控制台进行连接，绝对没有问题。

from clickhouse_driver import Client
client = Client(host='localhost')
client.execute('select * from default.table_name')

# [(4, 'four'), (5, 'five'), (1, 'one'), (2, 'two'), (3, 'three')]

更新：连接后stacktrace超时：

System.IO.IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
   at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)

   ...

部署clickhouse的docker compose。我不是dockerMaven，所以我对db很满意，我可以通过tabix web ui连接到它：

version: "3.7"
services:
  clickhouse:
    image: yandex/clickhouse-server
    ports:
    - "8123:8123"
    - "9000:9000"
    - "9009:9009"

    ulimits:
     nproc: 65535
     nofile:
      soft: 262144
      hard: 262144
 client:
    image: yandex/clickhouse-client
    command: ['--host', 'server']

更新：在连接到非本地cassandradb之后，问题消失了，这意味着连接到我的本地cassandradb（在docker容器中）有问题。
